DISCUSSION

(This Afternoon Through Saturday) Issued at 1103 AM MST Sun Mar 1 2026

Mild split flow can be expected most of this week. Warm Pac air will dominate the weather as arctic air shifts back northeast. Stalled frontal boundary will lift back northeast through Monday, as a central Rockies upper trough moves east into the Central Plains. The northern periphery of this system will clip the southern third of the FA later Monday int Tues, supporting mainly rain chances there. There is a small prob for freezing rain on the SD Plains subfreezing temps and precip times together Monday night, albeit small. Sharp cutoff to precip in the northern end of the system given very dry profiles and weak moisture transport. Mild weather will continue through Wed, the warmest day of the week. Given sunny skies, breezy winds and warm profiles, expect highs well into the 60s most places, with low 70s on the the Plains east of the BH. Another stronger upper trough will shift into the region Thur with an associated cold front. This system will bring a good chance of rain and some snow to the region. At this time, mainly rain can be expected outside of the BH where some accums are possible. After a cooler Friday, warmer air will move back into the region with mild and dry weather on track for next weekend.
